The airline removed the woman after several complaints from passengers.

Tension ran high on a Saturday flight from Baltimore to Seattle, when a woman asked her neighbor if he had been in town to celebrate or protest Donald Trump's inauguration. (The inauguration Friday was followed by Women's March worldwide on Saturday.) According to the passenger, Steve Kotesky, his response—"I came here to celebrate democracy, ma’am"—was met with a barrage of insults that led her to be later removed from the plane by airport police.

After the initial question, Kotesky began filming the interaction on his phone. According to Kotesky's video, he told flight attendants that his seat mate "called me names and insulted me just for sitting down on this seat, saying that I came here to celebrate today.” Allegedly, the woman called Kotesky a bigot and threatened to throw up on him. She later told the flight attendant that she wanted the Trump supporter, who was sitting in the window seat, to move. The flight attendant responded, “You don’t have that right.”

When another flight attendant came to bring the offending passenger and her husband, who was seated in the aisle, off the plane and back down the jetway, she initially refused. "No, I paid for this seat and I’m sitting in it. He is in my space,” the woman told the Alaska Airlines crew member, before being escorted off the flight with her husband and carry-on by airport police.

“We can confirm that a disruptive passenger was removed from flight 761 from Baltimore to Seattle prior to departure,” Alaska Airlines told BuzzFeed News in a statement. “The female passenger was insulting passengers in the boarding area and then onboard the aircraft. Several passengers expressed concerns about her behavior. We stand by our employees’ decision to remove the disruptive passenger."

According to Alaska Airlines, the couple was refunded for their flight but not rebooked on another flight with the airline.

This isn't the first time politics have led to verbal incidents on flights. Soon after the election, a Trump supporter was banned from Delta flights for life after a rant at 35,000 feet. A United Airlines pilot banned political chat over his flight's loudspeaker before a trip to Puerto Vallarta in November, saying, "Nobody is going to change their minds by arguing. And let's keep our opinions to ourselves, on this particular matter, at this particular time. When cooler heads prevail, we can talk and realize we're all human beings and we can all stick together and we can all pull for this country in our own way." With emotions already running high at 30,000 feet, that seems like sound advice.
